UNITED STATES` ELIJAH MGCOY, OF IGNIA, MICHIGAN, ASSIGNORJOF ONE-HALF HIS RIGHT l PATENT OFFICE..

TO WILLIAM J. STIFF, OF SAME PLAGE.

l IMPROVEMENT'IN STEAM-CYLINDER'LuBR|cA'roRs.

' Specification forming part of Letters Patent No.1173,03v2, dated February 1, 1876 application filed Y December `10, 1875.

To all whom it may concern:

Be it known that I, ELIJAH MGGOY, of Ionia, in the county of Ionia and State vof Michigan, have invented certain new and useful Improvements in Steam-Cylinder Lubri- I, cators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specitication. f

My invention relates to that class of steamcylinder lubricators in which the steam is al'- lowed to pass up through a central tube in the oil-cup, and the oil pass downward through the same tube; andthe nature of my invention consists in the construction and arrangement of said central tube with a regulator at its upper end, and an interior valve, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the sanne, I will now proceed to describe its construction and operation, referring to the annexed` drawing, in Which- Figure l is a central vertical section, and Fig. 2 is a cross-section on the line y y, Fig. l; and Fig. 3 is a cross-section on linea: w, Fig. l. l

A represents the central tube within the usual oil-cup, which tube communicates at its lower end with the interior of .the steamchest, in the ordinary manner. The upper portion of the tube A is enlarged, as shown at B, forming an interior valve-seat, a. In the upper end of' said enlarged portion B is screwed a regulatingtube,0, having a jam' nut, c', uponvit to hold it firmly at, any point desired, so as to make the central tube higher or lower, as desired. The lower portion of this tube vC is reduced in diameter,so that when it is inserted an oil-chamber, 70is formed between it and the tube B. The lower end of the regulatingtube C forms a valve-seat, b, and in the sides of said tube are small per'- forations .r m, as shown.

It will be understood that the central tube A has no lateral openings, so that when it is placed within the usual oil-cup no oil can reach the valve excepting that which'is passed in at the top of the regulating-tube, and

through the perforations in the bottom of said regulating-tube, by the displacement of oil corresponding to the amount of steam injected. v

d represents a double valve, provided with a valve-stem, c, projecting on both sides thereof'. This valve is placed in the space between the valve-seats a and b. Its normal po-` that an oil-reservoirprovided with a screwplug which is hollow only at its bottom, and perforated at that point to admit the oil, is not new, and hence I do not claim such as being, broadly, my invention 5 but with such latter inventions known to me the oil is admitted just above the valve, and as the steam condenses, and the water collectsin the bottom of the reservoir, and rises to the perforations, the oil is stopped, and water instead will pass down.

With my invention the regulating-tube C is hollow to its top, and oil is fed in through the top of this tube directly onto the valve, t

and the difficulty above described could not occur.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is'- The combination-of the chamber B, the regulating-tube C, open from top to bottom, and

having perforations 5v, and the valve d, with stem e and valve-seats c b, all constructed substantially as and for the purposes herein described. In testimony that I claim the foregoing as my owuI affix my signature in presence of two witnesses.
